Avast AntiTrack Premium is a privacy application designed to keep your identity safe from the latest online tracking techniques. To enable all program features, you need to install an additional extension on your internet browser. The first time you launch Avast AntiTrack Premium, it automatically checks for Google Chrome, Mozilla Firefox, and Opera browsers and prompts you to install the extension. If you skip this step, or need to install the extension later, follow the instructions in this article.

Browsers that are not installed on your PC do not have a slider, and are marked as (Not Installed).

To disable a browser extension, tap the green (ON) slider so that it changes to red (OFF).

When a browser extension is Not Enabled, Avast AntiTrack Premium continues to detect tracking attempts on this browser, but is unable to block them. Tracking attempts which weren't blocked are shown in your Tracking History on the Avast AntiTrack Premium dashboard:

To protect your privacy online and prevent targeted adds, we strongly recommend keeping the browser extension enabled for all browsers which are installed on your PC.
